Nissan Leaf. Manual - part 705

GI-32

< PRECAUTION >

PRECAUTIONS

• If old rubber hose is re-used, install hose clamp in its original posi-

tion (at the indentation where the old clamp was). If there is a trace

of tube bulging left on the old rubber hose, align rubber hose at

that position. 

• Discard old clamps; replace with new ones.

• After installing plate clamps, apply force to them in the direction of

the arrow, tightening rubber hose equally all around.

Air Conditioning

INFOID:0000000010122915

Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to

HA section “REFRIGERANT” for specific instructions.

How to Disconnect High Voltage

INFOID:0000000010122916

PROCEDURE FOR DISCONNECTING HIGH VOLTAGE

Be sure to follow the procedure below and disconnect the high voltage before performing inspection or servic-

ing of the high voltage system.
1. Turn power switch OFF.

CAUTION:

The worker must keep the intelligent key on his/her person.

2. Disconnect 12V battery negative terminal.
3. Remove service plug, following below procedure.
a. Insert a suitable tool under the RH rear corner of the access trim

cover (1) and pry up (2) to remove.

b. Remove the access cover bolts (1) and remove the cover (2).

c. Remove the service plug.

DANGER:

Touching high voltage components without using the appropriate protective equipment will

cause electrocution.

WARNING:

• Immediately insulate removed high voltage connectors and terminals with insulating tape.

• Be sure to put the removed service plug in your pocket and carry it with you so that another per-

son does not accidentally connect it while work is in progress.

CAUTIONS AS TO HIGH VOLTAGE

4. Wait for a minimum of approximately 10 minutes after the service plug is removed.

PROCEDURE FOR CONNECTING HIGH VOLTAGE

1. Check that 12V battery negative terminal is disconnected.
2. Install service plug as per the following steps.

DANGER:

Touching high voltage components without using the appropriate protective equipment will

cause electrocution.

WARNING:

• Immediately insulate removed high voltage connectors and terminals with insulating tape.

• Be sure to put the removed service plug in your pocket and carry it with you so that another per-

son does not accidentally connect it while work is in progress.

3. Connect 12V battery negative terminal.

High Voltage Precautions

INFOID:0000000010122917

WARNING:

• Because hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of elec-

tric shock, electric leakage, or similar accidents if the high voltage component and vehicle are han-

dled incorrectly. Be sure to follow the correct work procedures when performing inspection and

maintenance.

• Be sure to remove the service plug in order to shut off the high voltage circuits before performing

inspection or maintenance of high voltage system harnesses and parts.

• To prevent the removed service plug from being connected by mistake during the procedure, always

carry it in your pocket or put it in the tool box.

• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield, and glasses

before beginning work on the high voltage system.

• Clearly identify the persons responsible for high voltage work and ensure that other persons do not

touch the vehicle. When not working, cover high voltage parts with an insulating cover sheet or sim-

ilar item to prevent other persons from contacting them.

CAUTION:

There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the

service plug is removed. Therefore do not change the vehicle to READY status unless instructed to do

so in the Service Manual.

HIGH VOLTAGE HARNESS AND EQUIPMENT IDENTIFICATION

The colors of the high voltage harnesses and connectors are all orange. Orange “High Voltage” labels are

applied to the Li-ion battery and other high voltage devices. Do not carelessly touch these harnesses and

parts.

HANDLING OF HIGH VOLTAGE HARNESS AND TERMINALS

Immediately insulate disconnected high voltage connectors and terminals with insulating tape.

The vehicle contains parts that contain powerful magnets. If a person who is wearing a heart pace-

maker or other medical device is close to these parts, the medical device may be affected by the mag-

nets. Such persons must not perform work on the vehicle.

PROHIBITED ITEMS TO CARRY DURING THE WORK

Because this vehicle uses components that contain high voltage and powerful magnetism, do not carry any

metal products which may cause short circuits, or any magnetic media (cash cards, prepaid cards, etc.) which

may be damaged on your person when working.
